Enum ColumnFlag 

pub enum ColumnFlag {
    Mandatory,
    Hidden,
    IdField,
    TitleField,
    Searchable,
    Indexed,
    Label,
}

Column flags that define behavior and properties of columns.

Variants

Mandatory

Mandatory will require read/write operations to always have value for this field, it cannot be missing

Hidden

Hidden columns should be excluded from UI display

IdField

IdField marks this column as the primary identifier for the table

TitleField

TitleField marks this column as the display title/name for records

Searchable

Searchable marks this column as searchable in text searches

Indexed

Indexed marks this column as cheap to sort or filter on, hinting to generic UIs that they can offer sort headers and filter inputs without a performance penalty

Label

Label hints to generic UIs that this column is better shown as a small status tag attached to the record’s title than as its own column (e.g. a status / state field with a per-value color map)

Trait Implementations

impl Clone for ColumnFlag

fn clone(&self) -> ColumnFlag

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ColumnFlag

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ColumnFlag

impl Hash for ColumnFlag

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ColumnFlag

fn eq(&self, other: &ColumnFlag) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
